Hey guys i think ive got a problem, i have my a100 for a week now and i'm happy with it. But one time i used it, suddenly it reboots this was a few days ago. And just this moment i want to wake up it from sleep mode, but it was turned off, although it still has 50 % of battery. I think it's not that bad but i want to be sure that it is not a hardware problem. You have an advice?
